-
Medium 6.5
Large aggregation pipelines with a specific stage can crash mongod under default configuration
It may be possible to have an extremely long aggregation pipeline in conjunction with a specific stage/operator and cause a stack overflow due to the size of the stack frames used by that stage. If an attacker could cause such an aggregation to occur, they co…
-
Medium 6.4
MongoDB Java driver client-side field level encryption not verifying KMS host name
Specific versions of the Java driver that support client-side field level encryption (CSFLE) fail to perform correct host name verification on the KMS server’s certificate. This vulnerability in combination with a privileged network position active MITM attac…
-
Medium 5.4
Denial of Service and Data Integrity vulnerability in features command
An authenticated user without any specific authorizations may be able to repeatedly invoke the features command where at a high volume may lead to resource depletion or generate high lock contention. This may result in denial of service and in rare cases coul…
-
Medium 5.3
